wont hurt the engine to gut/cut. you might lose some low end.

 

what's the "non fouling" trick...??? how do u do it?

 

basically you get a o2 simulator that you replace your o2 sensor with. what it does is tell your PCM that your cats are just fine and it continues operating normally without throwing any codes.

o2 simsdont work on the hemi's...we are using sparkplug nonfoulers. drill one out to 1/2" and screw it into another nonfouler, then you screw the o2 sensor into the non fouler that was drilled out and then screw that into the exhaust pipe and hook up the o2..id say 99% of the time it works
